Application filed May 25, 1918. Serial No. 236,484.

To-LZZ whom t may concern.' Y D Be it known that L CHARLES Parr, a citi-l zen of the UnitedStates, and a resident or New York, in the county of New York and State of New York, haveinvented a certain new and useful Improvement inlltetaining-v lValls for Embankments, of which the folconstruction work, and which is especially' adaptable of being built of cement, in order to save the expense', time and labor incident to constructing such walls of stone. The invention consists essentially of providing a series of pockets with orificed walls on one face of an upwardly disposed wall member with a base adapted to be embedded at the edge of an embankment of earth, gravel and the like so that the wall will be anchored in the edge part of the embankment by itsmaterial being received in the pockets as well as in the orilcesof the walls of the pockets.

A further object of Vthe invention is to Aprovide a retaining wall adapted to be constructedso as to combine great strength and durability,^and which is susceptible .of being made in any suitable length and height.

A practical embodiment of the invention is represented in the accompanying drawing which forms a part of this specification in which similar characters of reference indicate corresponding parts in all the views, the said invention being more Jfully described 'hereinafter and Vthen pointed out in the claimsvat the end of the description. y

` In the drawing, Figure 1 is a fragmentary view, partly broken away, showing a detail section of one form of retaining wall embodying my invention taken on the line4 I-I of Fig. 2 as well as showing the manner of its use for holding the edge of an embankment. Fig. 2 is a fragmentary view, partly broken away, showing a front elevation of the wall. Y Y' Fig. 3 is a fragmentary view, Vpartly broken awayj showing a rear elevation ot the wall, and A i Fig. l is a fragmentary view, partly brokenaway, showing a perspective of part of-my improved wall. Y

The retaining wall has a longitudinally disposed base, as 10, which may be of any desired width, length and thickness, and protruding downwardly from the underside lengthwise of the edges of the base may be two flanges, as 11 and 12. Thebase 10 with the flanges 11 and 12 are partially, or entirely embedded in thev earth or gravel at the foot or edge of an embankment, as 13, when the wall is erected, in order to properly anchor the base.

To support the required portion of the edge of the embankment I provide a wall 14 which may be disposed vertically, or on an incline toward the embankment. This wall is arranged toextend preferably upwardl from the top of the base 1() over the iange 1l, and this wall may be of a length similar to the length or" the base, besides being of any desired height and thickness. The upper edge of the wall may terminate with a flange or ledgeg which overhangs one face or" the wall in. opposed relation to the em-A bankment, and this flange isa great deal narrower in width than the base 10. VThe wall proper may also, as occasion requires, be reinforced in strength by constructing Vit with superimposed lengthwise protruding portions, as 16 and 17, of different thicknesses, the lthickest portion being adjacent to the base 10, as shown.

4Projectino` at spaced intervals from the face of the wall lll as well as being disposed in opposition to the embankment are a number of web or extended members 18. These web members may be of any suitable number, besides vbeing of any desired thicknesses and widths so as to protrude the required distances from the wall 14. The web members- 18 are of heights whereby they extend vertically from the top of the base 10 to the overhanging ledge 15, and all of these members are constructed so that their free edges correspondingly taper from the edge 01' the base 10 which is over the flange 12 to the narrow ledge 15.

Extending lengthwise ot the wall 14.- between the web members 18, projecting preferably from the upper terminals or" the pro truding portions 16 and 17 oi" the wall are rows'orn longitudinally disposed ledges 19 and v2O. The ledges of the row 19 are in alinement, while the ledges of the row 20 are also in alinement. These rows of ledges` are constructed so as to be preferably spaced equal distances between thev base 10 andthe top ledge 15 of the wall, and all Vof the ledges may be of sizes so that their free edges terminate at the free edges of the ver.;

tical web members 18. By constructing the web members of the ledges to coact in-this manner, recesses or pockets,as 21, `are provided on one face of the wall 14 forv receiving the earth or gravelv of the embankment,

and serving to anchor the-wall to the ein-- bankment on the underside of the free edge of each of the ledges 19 and 2O is a depending flangey 21a. v j

The depending I flanges E211;L may be of widths so as to hang downwardly suitable distances from the ledges to form each ledge in 'somewhat a hook-shape Yfor serving to effectually gripthe material of the embankment. In each of the ledges 19 and 2O may be one or a-number of spaced openings, as 22, 23, 211, and in each of the web members 18, between the base 10 and the ledge1'9 may be an opening 25, while in each web memberbetween the ledges 19 and 20 may also be an opening 26. The openings 22, 23,2% 25, 26 may be of any ldesired shapes and sizes, though I prefer to make these opening substantially square in shape `and of sufficient sizes to allow the material V of the embankment to pass therethrough when the material is delivered into the pockets 21 of the wall `14.V The wall will thereby be 1 effectually anchored in the embankment by p making the pockets withorificed walls as well as by providing the flanges 21a -on the ledges 19 and 20.

In the foregoing description, I have embodied the preferred form of my invention,

but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle, or secrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as vfairly fall within the scope thereof. f

' i Having thus described my invention, I claim as new and desire to secure by Letters Patents-- f Y 1: In Lt-.retaining wall, the combiiuttionVV with a substantially flat horizontal base having a wall member extending upwardly subvstantia'l from thev forward edge thereof, of
